What's the weather like in Marmaris in September?Marmaris, which is on the Turquoise Coast in southwestern Turkey, has quite typical Mediterranean weather.

It’s the perfect time to visit if you'd rather avoid the scorching and busier July and August. Marmaris is in a sheltered bay on the Turkish Riviera, which stops northern and Mediterranean winds from cooling things down too much.
